I tried to beat the 41F changes with my last 2 applications (done the same day) - don't know how far ahead of the last minute rush I may have been, but I knew a lot of folks were going to wait right up until the last day before 41F changes to apply.
For all three times I've applied, The Silencer Shop's wait times have been on the money.
My Latest Experience (received 3 weeks ago):
Type: Form 4 Paper Trust
Mailed: 5-10-16
Stamps Received: 1-18-17
Total Wait Time: 8 months, 1 week, 1 day
I got caught up in the first rush a few years back - my original silencers took 8 months, 2 weeks, 2 days.
After that rush was over, I purchased another and it only took 3 months, 1 week, 2 days for approval, but somebody left it on their desk a while - took 4 months, 3 weeks, 2 days to arrive.
